I've tried to migrate on the 6.03.3 version, but i've still the linking problem.

Before installation i've removed previous version of tsilang 6.0.2
As state before my application is in C++ builder, I've installed the component with C++ installation but when i link the application
it said "unable to open tsilang_d2006r.bpi" and the file does not exist...

It looks like in your project configuration is used reference to tsilang_d2006r.bpi. You can edit project configuration file by removing this reference or change it to tsilang_c2006r.bpi if you need to use run-time packages.
